| Invitae | RCV001215303 | SCV001387040 | uncertain significance | Myofibrillar myopathy 5; Distal myopathy with posterior leg and anterior hand involvement; Hypertrophic cardiomyopathy 26; Dilated Cardiomyopathy, Dominant | 2023-02-16 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 1294 of the FLNC protein (p.Asn1294Ile). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with FLNC-related conditions. ClinVar contains an entry for this variant (Variation ID: 944815). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on FLNC protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
| Ambry Genetics | RCV003163650 | SCV003859304 | uncertain significance | Cardiovascular phenotype | 2022-11-15 | criteria provided, single submitter | clinical testing | The p.N1294I variant (also known as c.3881A>T), located in coding exon 22 of the FLNC gene, results from an A to T substitution at nucleotide position 3881. The asparagine at codon 1294 is replaced by isoleucine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
